FASTENER FOR STORM-SASH.

Application led .Tune 26, 1911.

To all whom t may concern Be it known that I, VILLIAM C. J. KURTH, a citizen of the United States, residing at Edgemont, in the county of Fall River and State of South Dakota, have invented a new and useful Fastener for Storm- Sash, of which the following is a specification.

The invention relates to improvements in windows.

The object of the present invention is to improve the construction of fastenerfor storm sash, and to provide a simple, inexpensive and efficient construction, adapted to permit a full length storm window or window screen to be easily and quickly applied in position from the inside, and capable of effectually preventing a storm sash or screen from rattling, and of securing a storm sash silifiicently tight to prevent frosting of the g ass.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacriiicing any of the advantages of the invention.

In the drawings z-Figure 1 is a. vertical sectional view of a window, provided with a. storm sash, constructed in accordance with Fig. 2 is a horizontal sectional view on the line 2 2 of Fig. 1. Fig. 3 is a vertical sectional view, taken substantially on the line 3 3 of Fig. 1. Fig. 4 is a perspective view of a full length window screen, constructed in accordance with this invention. Fig. 5 is a detail perspective view of one of the socket plates. Fig. 6 is a detail perspective view of one of the cam levers. Fig. `7 is a detail-perspective view of one of the keepers. Fig. 8 is a detail perspective view of one of the pivots and its attaching plate.

Like numerals of reference designate corresponding parts in all the gures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, l designates a full length storm sash or frame, provided at the top with spaced sockets providing bearing members 2 Specification of Letters Patent.

Serial No. 635,408;

for engaging wedge-shaped studs or keepers 3. The storm sash is securedvat the lower portion by combined bearing members and fastening devices, each composed of a cam lever 4 and a keeper 5 and adapted to maintain the storm sash in engagement with the studs 3. The sockets 2 consist of recesses formed in the spaced bars of the frame of the sash, and the latter is provided with metallic socket or bearing plates 6 let into the upper edge of the'frame of the sash at the inner sides of the sockets and provided with recesses 7, conforming to the configuration of the upper ends of the sockets and presenting metallic edges at three sides of the sockets. As there is no strain on the frame of the sash at the outer sides or walls of the sockets, it is unnecessary to reinforce the frame at such points.

The wedge-shaped studs or keepers are provided with integral upwardly extending threaded shanks 8, which are screwed into the window frame or casing 9' at the top thereof, and the said studs depend from the top of the window frame or casing at a. point beyond the upper andy lower window sashes 10 and 11, and they have fixed inner inclined edges or faces l2, which extend upwardly and inwardly from the lower edges of the studs, whereby when the sockets in the top of the frame of the sash are engaged with the fixed studs, the inclined faces thereof will force the sash inwardly into tight engagement with the outer or outside strips or beads 9'L of the window frame or casing. The outer strips or beads 9a of the window frame or casing form an outside stop for the storm sash and limit the inward movement of the same.

The keeper 5 consists of a plate secured by screws, or other suitable fastening devices to the side of the window frame or casing at the lower portion thereof, and provided with an inclined iiange 13 extending upwardly and inwardly, as clearly illustrated in Figs. 1 and 7 of the drawings. The cam lever 4 consists of a handle and a head 14, mounted on a pivot 15 of a plate 16,*secured by screws or other suitable fastening devices to the side of the frame of the storm sash. The head 14, which is provided with an opening 17 to receive the pivot l5, is cut4 to extend between the head and the frame, as clearly shown in Fig. 2 of the drawings. The head of the cam lever is provided with a tapered peripheral cam portion 19, adapted to present movable inclined engaging faces to the inclined flange 13 of the keeper', whereby the lower portion of the storm sash is drawn inwardly into tight engagement with the outside strips or beads 9? of the window frame or casing. 'Ihe fixed inclined flange of the keeper plate has its lower end arranged closer to the frame than its upper end, and when the tapered peripheral portion ofthe head of the cam lever. rides up4 the said inclined flange there is a double wedging action incident to the inclination of the flange and the taper of the cam lever operating to draw'the frame inwardly.

The storm sash is arranged within the outer portion of the window frame or casing and lits snugly against the same. It is adapted to be passed through the window from the inside andinay be readily engaged with the fixed studs at the topV of the window frame or casing, while grasping the sash by the stiles thereof. After the sash is engaged with the studs, it is drawn inward by means of the handles of the fastening devices, which are then in an upright position, as illustrated in Fig. t of the drawings to present the straight cut away side to the keepers so as to clear the same. The handles are then swung downward to engage the peripheral Vcam portions with the inclined flanges of the keepers, whereby the storm sash is drawn into tight engagement with the window frame or casing. The inclined faces ofthe lugs and the inclined flanges of the keepers cooperate in holding the storm sash tightly against the window frame, and the sash is held sufficiently tight to form a perfect dead air space so that frosting of the glass and rattling of the sash are prevented. The cam levers are located at opposite sides of the lower portion of the storm sash, and their handles are arranged in convenient position to be grasped by the operator in handling the sash from the interior. In practice storml sashes will be provided with a suitable Ventilating device, so that ventilation lnay be had without removingthe storm sash. The inward movement of the storm sash 1 causes its lower inclined edge 1fL to engage with the sill and force the'frame upwardly with respect to the depending studs 3, whereby a tight engagement of the frame of the storm sash with the window casing f keepers with a double wedging action is secured. rIhe inclined faces of the studs and the lower fastening devices also enable the storm sash to be held tightly in place both at the beginning of the winter season, when the woodwork is in more or less a shrunken condition, and also after the woodwork swells through exposure to the weather.

The improvements are equally applicable to a full length window screen 20, as illustrated in Fig. l of the drawings.V The frame of the screen is provided at thetop with the said sockets 2 and the socketplates 6, and it is equipped at the lower portion with the cam levers 4: for engaging the,

flanges 13 of the keepers 5. The fastening means for the storm sash and the window screen will enable either to be easily and quickly applied to a window, and a window screen may be instantly substituted for a storm sash and vice versa.

Having thus fully described my invention, what I claim as new and desire to secure by rLetters Patent, is-

rIhe combination with a window 'casing having the usual outwardly inclined sill, of

upper and lower keepers in said casing provided with inner faces inclining inwardly and upwardly, said lower keepers comprising flat plates secured to the inner sides of the window casing and having inturned flanges inclined inwardly and upwardly, a frame adapted to fit-in the outer side of the casing against the outside bead thereof, upper and lower bearing members on the frame for engagement with said keepers, said lower members being cut away at one side, and handles on the lower members for Vturning the same out ofthe path of the lower keepers during the positioning of the bearing members in line with the keepers, the lower bearing members having cams thereon adapted to work against the Vlower keepers, upon the turning of the handles to draw said frame inwardly over said inclined sill and raise the frame, the upper and lower directing the frame inwardly against the outside bead during such upward movement to bind the frame throughout its length against said bead.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

WILLIAM CARL JOHN KUR'lll.
